This was just a fun project to test the functionality of the Fireball V90 CNC that I had just built. I had an old circuit board from a CD-ROM sitting on the desk and decided to try to cut some letters into it. The results were quite good. Have a look at how the chips got cut in half. http://hackedgadgets.com/2009/04/18...tes-hacked-gadgets-into-an-old-circuit-board/
looks good, nice little cnc machine Hope you had a mask on pcbs are nasty stuffs, plus the chips and such.
Nice seeing the milled out chip, just dont hit any ceramic chips or your endmill wont know what hit it
